To any Dividend Investors in the community, what are some/top 3 advice you have for those who are getting into dividend investing like myself?

Yes, time in the market is certainly critical in reaping the benefits from compounding, and you will gain more if you reinvest dividends. I might add that it is not just for dividend investing, but also growth investing.

But compounding does cut both ways. If you pick a declining stock, the loss is compounded too, and might not be recovered by collecting dividends (if any).

Here is what I would look at for dividend stocks:

1. Does the company have a moat to keep a stable revenue and profits among its competitors?

2. Does the company have a track record of increasing its dividends over a long period of time (what some called Dividend Aristocrats)?

3. Can the company's Free Cash Flow sustain its dividend payouts?
